     .count-table   таблица счётчика с закрытой строкой — ведущий приём
     .growth-table  во сколько раз выросла работа при удвоении входа
     .op-listing    листинг с подсветкой строки, которая выполняется чаще всего
     .versus        два решения одной задачи бок о бок с ценой каждого
     .timer-card    экран практики: таймер и кнопка «Показать файл»
